SPECIFICATION forming part of Letters Patent No. 677,956, dated J' uly 9, 1901. Application filed February 45 190,1. Serial No, 45,955. (No model.)

T0 all whom it may concerwj Be it known that I, RowLAND J. DARNELL, a citizen of the United States,residing at Mernphis, Shelby county, State of Tennessee, have invented certain new and useful Improve'- ments in Machines for Making Wire Bale-Tie f Loops, of which the following is a specification.

My invention relates to machines for form ing wire bale-tie loops, and more especially -to machines which form loops by bending and wrapping one end of the wire around the body of same without twisting them together and therebyweakeningthem. Suchatieis'shown in process of being formed in the drawings hereto appended.

The object of my invention isto provide a simple and efficient machine for making wire bale-tie loops.

It is my especial object, further, to provide a machine to make the form of bale-tie'loop hereinbefore referred to.

Heretofore in machines of this class it has been customary to form a loop approximating more or less to a circular form and to then catch this loop and the two parts of wire folded together and to complete the loop by twisting them together.

My machine has for its object to form the loop or eye carefully and having so formed it to wrap the free end of the wire around the body of same, and thereby finish the loop without in any way damaging the wires by an injurious twisting process.

In the drawings, Figure 1 is a perspective View of the machine from the rear and side. Fig. 2 is a section on the line II II of Figs. 1 and 3. Fig. 3 is a partial sectional elevation on the line III III of Fig. 2. Fig. 4 is a sectional elevation, partially in detail, to show the wrapping-spindle in position to begin the wrapping of the free end of the wire around the body of same to complete the loop. Fig. 5 is a fragmental elevation to show action of a detail.

Referring now to the drawings, in which like parts are indicated by like numerals in all the views, l `is the base or foundation plate. A tailstock 2 is mounted ou said base-plate and carries a mandrel 3, axially fixed but movable longitudinally, so that it may be withdrawn to release the wire loop or eye 4,

formed around it, in the manner hereinafter to be more fully set forth. 5 is a handle on this mandrel 3, which is grasped to withdraw same. 6 is a collar fastened on said mandrel and acted on by a spring 7 to hold the mandrel in place and to return it to place when it has been withdrawn to drop the finished loop 4. The tail-stock'2 is hollowed out to carry the spring 7, which'is held in place by a collar 8, which I have shown screwed in.

Opposite the mandrel 3 and axially in line therewith is a rotatable oye-forming spindle 9, which is used to form the loop 4. This eye-formin g spindle is carried by bearings 10, which are fastened to the base 1, as the tailstock is. This spindle 10 is hollow at 11 to receive the mandrel 3 and is slidably mounted in the said bearings 10 and the pulley 12, which is keyed on it with a feather-key sliding in a keyway in the spindle.

13 is a loosely-mounted hand-grip for forc- 9 when the hand-grip 13 is released after the loop 4 hasy been completed.

16 is a cord or belt fastened to the pulley 12 by a rivet 17 and wrapped twice around l said pulley, so that a pull in one direction will rotate this pulley two turns and a pull in the opposite direction will rotate it back to its original position. One end of this belt or cord passes over the pulley 18, which is supported by Va bracket 19 and descending thence through a hole 2O in the base-plate l is fastened to a weight`(not shown) to retract the cord, and thereby rotate the pulley 12 and spindle 9, on which it is fastened, to their original position when the loop or eye 4 has been finished. The other end of the cord 16 (designated beneath the base as 2l) is fastened to a treadle or like means, (not shown,) by which it may be depressed sufficiently to rotate pulley-12 and spindle 9 one, two, or more turns, as the case may be. y

22 is a notch or slot formed in the end of the spindle 9 to catch the wire 14 and make the loop 4. 'To form this loop the cord 16 is so arranged that the spindle receives nearly are such as to take the wire in the horizontal IDO the mandrel and lthe eye-formingspindle andl at right angles to them. It is longitudinally fixed in bearings 24, which are carried by a bracket 25, adapted to slide in a dovetail guide 26 on the base l.

27 is a handle pivoted to a standard 2S on the base and fastened by a pin and cotter The bearing in 29 to the sliding bracket 25. the handle 27 at thestandard 23 is slotted to 4allowsuiiicient play for the circular sweep of the handle.

The wrappingspindle 23 is constantly rotated by a belt 30, passing around a pulley 3l on said spindle, and has a notch orslot 32,

similar to that on the eye-forming spindle, to wrap the free end 33 of the Wire around the Y body of the wire 34 after the loop or eye 4 has `been formed. This spindle is made hollow,

and the wire 34 for the ties enters centrally `through it. to permit this spindle to come sufficiently close to catch the wire. and begin wrapping the free end 33 of same.

36 is a clamp to hold the wire during the entire process of forming the loop or eye 4 and of wrapping the free end 33. This clamp is normally -heldaway from the Vlower block 37 ofthe clamp by a spring 38. (Shown in Fig.

2.) This clamp is held in place and guided.

`by ears 39, which extend upward from the block 37 on each `side and serve also to carry a bolt 40, on which an eccentric clamping-handle 4l is pivoted.

Holes 42 permit the `passage of the wire through the ears 39. The block 37 is bolted vto the base l.

In Figs. 2and 3 I show the free end 33 of the wires extending directly upward, the

wrapping not having been com pleted,as shown in theseiigures, and in Fig. 4 I show thewrapping-spindle 23 in position to begin.

(especiallyshown in Fig. 5.) is aguide 'for the free end 33 of the wire during the process of forming the loop 4. In making this loop AI find that the free end '33 of the wiresometimes has a tendency to go behind the body-' wire 34, in which case the operation of making the loop is effectually blocked. vent sucha contingency, I make use of the guide 43. This guide is pivoted at 44 and is thrown forward byra earn 45,'carried by the sliding bracket 25, when the bracket has been drawn back after completing the wrapping of thefrceend 33, and when -so thrown forward the upper end of the guide passes under the wire 34 and beyond same, so that the free end of the wire strikes the forward edge of the guide and is directed past the bodywire 34. When the bracket 25 is moved for- 'Ihe tail-stock is cutaway at 35 ward, however, the cam 45 depresses the L-A shaped arm of the guide 43 and withdraws same into the dotted position shown in Fig. 5, out of the way of the wrapping-spindle 23.

Means for cutting the wire to length and for feeding and measuring same are not shown herein.

In operation the wire is moved forward un# til the free end projects the proper distance beyond the mandrel 3 in the dotted position 14. The clamp 3G is set to hold the wire, and the eye-forming spindle is pushed forward by means of the hand-wheel 13 until the notch or slot 22 engages the wire 33. The belt 2l is then pulled downward and the spindle 9 thereby rotated until the free end 33 comes into the position shown in Fig. 4, the guide 43 forcing the end 33 to pass the body 34of the wire. The belt 2l is then released, and the belt 16 rotates the spindle 9 back to its former position. The wrapping-spindle 23 is next moved forward by means of the handle 27 until the notch 32 engages the free end 33 of the wire, as shown in Fig. 4. As soon as this notch catches the end 33 the handle 27 is released. The spindle 23, rotating rapidly, wraps or winds the free end 33 of the wire around the body-wire 34 and as the spiral is thus formed is forced back by it until the end is reached. The mandrel 3 is next pulled back and the finished loop dropped off. The desired length of wire is measured and the tie cut off, leaving the free end ready to be formed into another loop.

Various changes in the details of my invention may be made without departing from the same. The slot 22 in the spindle 9 and the slot 32 in the Wrapping-spindle may be modified in form, and other like detail changes not affecting the merits of the invention `may be made.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent of the "United States, is.-
